# CONFIG_INTERFACE
#
# The configuration interface is a series of menus or dialog boxes that
# allows you to change all the settings that control Bochs's behavior.
# There are two choices of configuration interface: a text mode version
# called "textconfig" and a graphical version called "wx".  The text
# mode version uses stdin/stdout and is always compiled in.  The graphical
# version is only available when you use "--with-wx" on the configure 
# command.  If you do not write a config_interface line, Bochs will 
# choose a default for you.
#
# NOTE: if you use the "wx" configuration interface, you must also use
# the "wx" display library.
#=======================================================================
config_interface: textconfig

#=======================================================================
# DISPLAY_LIBRARY
#
# The display library is the code that displays the Bochs VGA screen.  Bochs 
# has a selection of about 10 different display library implementations for 
# different platforms.  If you run configure with multiple --with-* options, 
# the display_library command lets you choose which one you want to run with.
# If you do not write a display_library line, Bochs will choose a default for
# you.
#
# The choices are: 
#   x              use X windows interface, cross platform
#   win32          use native win32 libraries
#   carbon         use Carbon library (for MacOS X)
#   beos           use native BeOS libraries
#   macintosh      use MacOS pre-10
#   amigaos        use native AmigaOS libraries
#   sdl            use SDL library, cross platform
#   svga           use SVGALIB library for Linux, allows graphics without X11
#   term           text only, uses curses/ncurses library, cross platform
#   rfb            provides an interface to AT&T's VNC viewer, cross platform
#   wx             use wxWindows library, cross platform
#   nogui          no display at all
#
# NOTE: if you use the "wx" configuration interface, you must also use
# the "wx" display library.

# F0000-FFFFF) and the videobios (located at C0000-C7FFF).
# Those ROM images will be initialized by the bios if they contain 
# the right signature (0x55AA).

#   journal=    optional filename of the redolog for undoable and volatile disks
#   
# Point this at a hard disk image file, cdrom iso file, or physical cdrom
# device.  To create a hard disk image, try running bximage.  It will help you
# choose the size and then suggest a line that works with it.
#
# In UNIX it may be possible to use a raw device as a Bochs hard disk, 
# but WE DON'T RECOMMEND IT.  In Windows there is no easy way.
#
# In windows, the drive letter + colon notation should be used for cdroms.
# Depending on versions of windows and drivers, you may only be able to 
# access the "first" cdrom in the system.  On MacOSX, use path="drive"
# to access the physical drive.
#
# The path, cylinders, heads, and spt are mandatory for type=disk
# The path is mandatory for type=cdrom
#
# Default values are:
#   mode=flat, biosdetect=auto, translation=auto, model="Generic 1234"

# IPS:
# Emulated Instructions Per Second.  This is the number of IPS that bochs
# is capable of running on your machine.  Read the note in config.h
# on how to find this.  Make sure to recompile after.
#
# IPS is used to calibrate many time-dependent events within the bochs 
# simulation.  For example, changing IPS affects the frequency of VGA
# updates, the duration of time before a key starts to autorepeat, and 
# the measurement of BogoMips and other benchmarks.
#
# Examples:
# Machine                                         Mips
# ________________________________________________________________
# 650Mhz Athlon K-7 with Linux 2.4.4/egcs-2.91.66 2 to 2.5 Mips
# 400Mhz Pentium II with Linux 2.0.36/egcs-1.0.3  1 to 1.8 Mips
# 166Mhz 64bit Sparc with Solaris 2.x             approx 0.75 Mips
# 200Mhz Pentium with Linux 2.x                   approx 0.5 Mips

# CLOCK:
# This defines the parameters of the clock inside Bochs:
#
#  SYNC:
#  TO BE COMPLETED (see Greg explaination in bug #536329)
#
#  TIME0:
#  Specifies the start (boot) time of the virtual machine. Use a time 
#  value as returned by the time(2) system call. If no time0 value is 
#  set or if time0 equal to 1 (special case) or if time0 equal 'local', 
#  the simulation will be started at the current local host time.
#  If time0 equal to 2 (special case) or if time0 equal 'utc',
#  the simulation will be started at the current utc time.
#
# Syntax:
#  clock: sync=[none|slowdown|realtime], time0=[timeValue|local|utc]

# LOG:
# Give the path of the log file you'd like Bochs debug and misc. verbage
# to be written to.  If you really don't want it, make it /dev/null. :^(
#
# Examples:
#   log: ./bochs.out
#   log: /dev/tty
#=======================================================================
#log: /dev/null
log: bochsout.txt

#=======================================================================
# LOGPREFIX:
# This handles the format of the string prepended to each log line.
# You may use those special tokens :
#   %t : 11 decimal digits timer tick
#   %i : 8 hexadecimal digits of cpu0 current eip
#   %e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
#   %d : 5 characters string of the device, between brackets
# 
# Default : %t%e%d

#=======================================================================
# LOG CONTROLS
#
# Bochs now has four severity levels for event logging.
#   panic: cannot proceed.  If you choose to continue after a panic, 
#          don't be surprised if you get strange behavior or crashes.
#   error: something went wrong, but it is probably safe to continue the
#          simulation.
#   info: interesting or useful messages.
#   debug: messages useful only when debugging the code.  This may
#          spit out thousands per second.
#
# For events of each level, you can choose to crash, report, or ignore.
# TODO: allow choice based on the facility: e.g. crash on panics from
#       everything except the cdrom, and only report those.
#
# If you are experiencing many panics, it can be helpful to change
# the panic action to report instead of fatal.  However, be aware
# that anything executed after a panic is uncharted territory and can 
# cause bochs to become unstable.  The panic is a "graceful exit," so
# if you disable it you may get a spectacular disaster instead.
#=======================================================================
panic: action=ask
error: action=report
info: action=report
debug: action=ignore
#pass: action=fatal

#=======================================================================
# DEBUGGER_LOG:
# Give the path of the log file you'd like Bochs to log debugger output.
# If you really don't want it, make it /dev/null or '-'. :^(

#=======================================================================
# COM1:
# This defines a serial port (UART type 16550A). You can specify a device
# to use as com1. This can be a real serial line, or a pty.  To use a pty
# (under X/Unix), create two windows (xterms, usually).  One of them will
# run bochs, and the other will act as com1. Find out the tty the com1
# window using the `tty' command, and use that as the `dev' parameter.
# Then do `sleep 1000000' in the com1 window to keep the shell from
# messing with things, and run bochs in the other window.  Serial I/O to
# com1 (port 0x3f8) will all go to the other window.
#=======================================================================
#com1: enabled=1, dev=/dev/ttyp9


#=======================================================================
# PARPORT1:
# This defines a parallel (printer) port. When turned on and an output file is
# defined the emulated printer port sends characters printed by the guest OS
# into the output file. On some platforms a device filename can be used to
# send the data to the real parallel port (e.g. "/dev/lp0" on Linux, "lpt1" on
# win32 platforms).
#
# Examples:
#   parport1: enabled=1, file="parport.out"
#   parport1: enabled=1, file="/dev/lp0"
#   parport1: enabled=0
#=======================================================================
parport1: enabled=1, file="parport.out"

#=======================================================================
# SB16:
# This defines the SB16 sound emulation. It can have several of the
# following properties.
# All properties are in the format sb16: property=value
# midi: The filename is where the midi data is sent. This can be a
#       device or just a file if you want to record the midi data.
# midimode:
#      0=no data
#      1=output to device (system dependent. midi denotes the device driver)
#      2=SMF file output, including headers
#      3=output the midi data stream to the file (no midi headers and no
#        delta times, just command and data bytes)
# wave: This is the device/file where wave output is stored
# wavemode:
#      0=no data
#      1=output to device (system dependent. wave denotes the device driver)
#      2=VOC file output, incl. headers
#      3=output the raw wave stream to the file
# log:  The file to write the sb16 emulator messages to.
# loglevel:
#      0=no log
#      1=only midi program and bank changes
#      2=severe errors
#      3=all errors
#      4=all errors plus all port accesses
#      5=all errors and port accesses plus a lot of extra info
# dmatimer:
#      microseconds per second for a DMA cycle.  Make it smaller to fix
#      non-continous sound.  750000 is usually a good value.  This needs a
#      reasonably correct setting for IPS.
#
# For an example look at the next line:
#=======================================================================

#sb16: midimode=1, midi=/dev/midi00, wavemode=1, wave=/dev/dsp, loglevel=2, log=sb16.log, dmatimer=600000

#=======================================================================
# VGA_UPDATE_INTERVAL:
# Video memory is scanned for updates and screen updated every so many
# virtual seconds.  The default is 300000, about 3Hz.  This is generally
# plenty.  Keep in mind that you must tweak the 'ips:' directive
# to be as close to the number of emulated instructions-per-second
# your workstation can do, for this to be accurate.
#
# Examples:
#   vga_update_interval: 250000
#=======================================================================
vga_update_interval: 300000

# using for Winstone '98 tests
#vga_update_interval:  100000

#=======================================================================
# KEYBOARD_SERIAL_DELAY:
# Approximate time in microseconds that it takes one character to
# be transfered from the keyboard to controller over the serial path.
# Examples:
#   keyboard_serial_delay: 200
#=======================================================================
keyboard_serial_delay: 250

#=======================================================================
# KEYBOARD_PASTE_DELAY:
# Approximate time in microseconds between attempts to paste
# characters to the keyboard controller. This leaves time for the
# guest os to deal with the flow of characters.  The ideal setting
# depends on how your operating system processes characters.  The
# default of 100000 usec (.1 seconds) was chosen because it works 
# consistently in Windows.
#
# If your OS is losing characters during a paste, increase the paste
# delay until it stops losing characters.
#
# Examples:
#   keyboard_paste_delay: 100000
#=======================================================================
keyboard_paste_delay: 100000

#=======================================================================
# FLOPPY_COMMAND_DELAY:
# Time in microseconds to wait before completing some floppy commands
# such as read/write/seek/etc, which normally have a delay associated.
# I had this hardwired to 50,000 before.
#
# Examples:
#   floppy_command_delay: 50000
#=======================================================================
floppy_command_delay: 500

#=======================================================================
# MOUSE: 
# This option prevents Bochs from creating mouse "events" unless a mouse
# is  enabled. The hardware emulation itself is not disabled by this.
# You can turn the mouse on by setting enabled to 1, or turn it off by
# setting enabled to 0. Unless you have a particular reason for enabling
# the mouse by default, it is recommended that you leave it off.
# You can also toggle the mouse usage at runtime (middle mouse button on
# X11 and SDL, F12 on Win32).
#
# Examples:
#   mouse: enabled=1
#   mouse: enabled=0
#=======================================================================
mouse: enabled=0

#=======================================================================
# private_colormap: Request that the GUI create and use it's own
#                   non-shared colormap.  This colormap will be used
#                   when in the bochs window.  If not enabled, a
#                   shared colormap scheme may be used.  Not implemented
#                   on all GUI's.
#
# Examples:
#   private_colormap: enabled=1
#   private_colormap: enabled=0
#=======================================================================
private_colormap: enabled=0

#=======================================================================
# fullscreen: ONLY IMPLEMENTED ON AMIGA
#             Request that Bochs occupy the entire screen instead of a 
#             window.
#
# Examples:
#   fullscreen: enabled=0
#   fullscreen: enabled=1
#=======================================================================

# ne2k: NE2000 compatible ethernet adapter
#
# Examples:
# ne2k: ioaddr=IOADDR, irq=IRQ, mac=MACADDR, ethmod=MODULE, ethdev=DEVICE, script=SCRIPT
#
# ioaddr, irq: You probably won't need to change ioaddr and irq, unless there
# are IRQ conflicts.
#
# mac: The MAC address MUST NOT match the address of any machine on the net.
# Also, the first byte must be an even number (bit 0 set means a multicast
# address), and you cannot use ff:ff:ff:ff:ff:ff because that's the broadcast
# address.  For the ethertap module, you must use fe:fd:00:00:00:01.  There may
# be other restrictions too.  To be safe, just use the b0:c4... address.
#
# ethdev: The ethdev value is the name of the network interface on your host
# platform.  On UNIX machines, you can get the name by running ifconfig.  On
# Windows machines, you must run niclist to get the name of the ethdev.
# Niclist source code is in misc/niclist.c and it is included in Windows 
# binary releases.
#
# script: The script value is optionnal, and is the name of a script that 
# is executed after bochs initialize the network interface. You can use 
# this script to configure this network interface, or enable masquerading.
# This is mainly useful for the tun/tap devices that only exist during
# Bochs execution. The network interface name is supplied to the script
# as first parameter

# KEYBOARD_MAPPING:
# This enables a remap of a physical localized keyboard to a 
# virtualized us keyboard, as the PC architecture expects.
# If enabled, the keymap file must be specified.
# 
# Examples:
#   keyboard_mapping: enabled=1, map=gui/keymaps/x11-pc-de.map
#=======================================================================
keyboard_mapping: enabled=0, map=

#=======================================================================
# KEYBOARD_TYPE:
# Type of keyboard return by a "identify keyboard" command to the
# keyboard controler. It must be one of "xt", "at" or "mf".
# Defaults to "mf". It should be ok for almost everybody. A known
# exception is french macs, that do have a "at"-like keyboard.
#
# Examples:
#   keyboard_type: mf
#=======================================================================
#keyboard_type: mf

#=======================================================================
# USER_SHORTCUT:
# This defines the keyboard shortcut to be sent when you press the "user"
# button in the headerbar. The shortcut string can be a combination of
# these key names: "alt", "bksp", "ctrl", "del", "esc", "f1", "f4", "tab"
# and "win". Up to 3 keys can be pressed at a time.
#
# Example:
#   user_shortcut: keys=ctrlaltdel
#=======================================================================
#user_shortcut: keys=ctrlaltdel

#
# The following directives are DEPRECATED 
# Please convert them to the new syntax  or remove them
#
#=======================================================================

#=======================================================================
#
# The DISKC option is deprecated. Use ATA* options instead.
#
# DISKC: file=, cyl=, heads=, spt=
# Point this at a hard disk image file.  To create 
# a hard disk image, try running bximage.  It will help you choose the
# size and then suggest a diskc line that works with it.
#
# In UNIX it may be possible to use a raw device as a Bochs hard disk, 
# but WE DON'T RECOMMEND IT.  In Windows there is no easy way.
#
# Examples:
#   diskc: file=10M.sample, cyl=306, heads=4, spt=17
#   diskc: file=20M.sample, cyl=615, heads=4, spt=17
#   diskc: file=30M.sample, cyl=615, heads=6, spt=17
#   diskc: file=46M.sample, cyl=940, heads=6, spt=17
#   diskc: file=62M.sample, cyl=940, heads=8, spt=17
#   diskc: file=112M.sample, cyl=900, heads=15, spt=17
#   diskc: file=483M.sample, cyl=1024, heads=15, spt=63
#=======================================================================
#diskc: file="30M.sample", cyl=615, heads=6, spt=17

#=======================================================================
#
# The DISKD option is deprecated. Use ATA* options instead.
#
# DISKD:
# See DISKC above for syntax
#
# NOTE: diskd and cdromd must not be used together!
#=======================================================================
#diskd: file="diskd.img", cyl=615, heads=6, spt=17

#=======================================================================
#
# The CDROMD option is deprecated. Use ATA* options instead.
#
# CDROMD:
#
# cdromd: dev=/dev/cdrom, status=inserted
# cdromd: dev=/dev/cdrom, status=ejected
# cdromd: dev=e:, status=ejected
#
# In windows, the drive letter + colon notation should be used for cdroms.
# Depending on versions of windows and drivers, you may only be able to 
# access the "first" cdrom in the system.  On MacOSX, use path="drive"
# to access the physical drive.
#
# NOTE: diskd and cdromd must not be used together!
#=======================================================================
#cdromd: dev=D:, status=inserted
#cdromd: dev=/dev/cdrom, status=inserted
#cdromd: dev="drive", status=inserted

#=======================================================================
#
# The TIME0 directive is DEPRECATED. Use the CLOCK directive instead
#
# TIME0:
# Specifies the start (boot) time of the virtual machine. Use a time 
# value as returned by the time(2) system call. If no time0 value is 
# set or if time0 equal to 1 (special case), the simulation will be
# started at the current time of the host. 
#
# Examples:
#   time0: 1           # Now
#   time0: 315529200   # Tue Jan  1 00:00:00 1980
#   time0: 631148400   # Mon Jan  1 00:00:00 1990
#   time0: 938581955   # Wed Sep 29 07:12:35 1999
#   time0: 946681200   # Sat Jan  1 00:00:00 2000
#=======================================================================
#time0: 938581955

#=======================================================================
#
# The PIT directive is DEPRECATED. Use the CLOCK directive instead
#
# PIT:
# The PIT is the programmable interval timer.  It has an option that tries to
# keep the PIT in sync with real time.  This feature is still experimental,
# but it may be useful if you want to prevent Bochs from running too fast, for
# example a DOS video game.  Be aware that with the realtime pit option, your
# simulation will not be repeatable; this can a problem if you are debugging.
#=======================================================================
#pit: realtime=1

# NEWHARDDRIVESUPPORT: enabled=[0|1]
# The old harddrive code is not maintened any more.
